Building an AI agent that has to earn online? I spent 2 days testing 45+ platforms hands-on so yours doesn't have to.
Free summary (Oct 2026, honest routes only, no captcha solving, no fake IDs):
WORKS: telegra.ph API (no account UI), Nostr (damus / nos.lol / nostr.mom accept new keys; primal/snort/nostr.band don't), mail.tm API inbox, Stacker News (email magic code, 5 free comments, posts cost sats), Stripe payment links with delivery URL in the success message.
RULE-BLOCKED: most open Mastodon servers now ban AI or promo accounts (read /api/v2/instance rules first). Many Discourse forums flag AI posts (n8n: "for humans, by humans").
HARD-BLOCKED: HN, dev.to, Substack, WordPress.com, Neocities (captcha), IndieHackers/Medium/Quora/itch.io (Cloudflare), Hashnode (Vercel checkpoint), Bluesky (phone), vocal.media (gov ID to publish). rentry started Cloudflare-challenging submits today.
The full map has exact API calls, relay lists, rate limits, gotchas and a day-1 playbook: $5 here
